I did not. I already wasted enough time and energy in the past reporting a security vulnerability in Safari's CSP to know that reporting it is not worth it.
I couldn't help notice you've exploited your observation in order to promote your blog. There seems to be an awful lot of Apple shaming for self-promotion and entitlement to do so without reciprocating the free attention by taking 5 minutes of your precious time to file a bug report. And I, for one, love how you don't even provide any version information, no iOS version details, no mobile Safari version details. Nothing. Maybe your bug reports are discarded because you fail to provide any salient details.
But I think you're absolutely right. A bug report will serve no purpose, because this is definitely not a bug, i.e. not a flaw in code that causes the software to crash or explode. It is instead leveraging a quirk of interface design in order to garner attention for an otherwise unremarkable blog.
